  • Reverse Osmosis - an overview

    High-efficiency RO (HERO™) is a patented process used in UPW production at semiconductor plants or where post-RO IX polishers (MBIX) are regenerated based on sodium and especially, silica and boron breakthrough [13]. The process achieves high rejection of silica, TOC and boron with RO, thereby reducing the load on MBIX polisher resins (or EDI units).
